Makes available, for the first time in English translation, four of the principal narrative sources for the history of the Spanish kingdom of Leon-Castile during the eleventh and twelfth centuries. Three chronicles focus primarily upon the activities of the kings of Leon-Castile as leaders of the Reconquest of Spain from the forces of Islam, and especially upon Fernando I (1037-65), his son Alfonso VI (1065-1109) and the latter's grandson Alfonso VII (1126-57). The fourth chronicle is a biography of the hero Rodrigo Diaz, better remembered as El Cid, and is the main source of information about his extraordinary career as a mercenary soldier who fought for Christian and Muslim alike. Covers the fasincating interaction of the Muslim and Christian worlds, each at the height of their power. Each text is prefaced by its own introduction and accompanied by explanatory notes.
